PROBLEM TO BE SOLVED: To provide a method of driving a light source capable of meeting the Adobe RGB color space. SOLUTION: Light generated by a light source is sensed in order to detect color coordinates of a red color, color coordinates of a green color and color coordinates of a blue color, a light source color space defined by the color coordinates of the red, green and blue colors is determined whether it covers a reference color space defined by red reference color coordinates, green reference color coordinates and blue reference color coordinates, color temperature of the light generated by the light source is controlled so that the light source color space covers the reference color space when the light source color space does not cover the reference color space.
